Benefits of technology

[0024]The subject of the invention is also a method of attaching a motor vehicle opening leaf by means of such an attachment device, this method being simple to carry out and provides safe and rapid adjustment of the position of the opening leaf hinges.
[0026]An attachment method of this kind thus eliminates an operation of adjusting the doors during mounting and ensures effective mounting right from the start.

Problems solved by technology

However, such plastic components do not support the panels effectively on the door casing during the attachment of the hinges and the mounting of the door, and risk in particular dropping if they come into contact with the M8 screws, which are integral with the panels.
However, such a hook system for attaching the panel has many drawbacks, in particular a complex manufacturing method for integrating the hook into the panel, and mounting which can come apart, since the hook can come out of the panel.
Furthermore, a solution of this kind is not enough, in particular for dealing with the various problems associated with attaching the panels and adjusting the position of the panels with respect to the door casing.

Embodiment Construction

[0032]With reference to FIGS. 1 to 6, the attachment device 10 according to the invention is intended to attach an opening leaf, for example a side door or a trunk lid (or tailgate), to the body of a motor vehicle (not shown in the figures for reasons of clarity). In the particular embodiment shown in FIG. 1, only an upper hinge 11 of a motor vehicle side door, which is associated with an upper panel mounted on a framework of the door, is shown for reasons of clarity, the following description applying equally to a conventional lower hinge and to a lower panel (FIGS. 5 and 6).

[0033]In FIG. 1, the hinge 11 has conventionally a first bracket 12 which is pressed against a framework of the door, namely the door casing 19, and which comprises two attachment orifices 13. The attachment orifices 13 are, for example, oblong holes, so as to enable adjustment during the positioning of the hinge 11. The latter also has a second bracket 14, which is mounted such that it can rotate with respect ...

Abstract

A device for attaching a door leaf to an automobile body including: at least one plate combined with at least one hinge of the door leaf and mounted on a framework of the door leaf so that at least one screw connected to the plate interacts with a hole combined with the hinge and protrudes through the door leaf framework; a bonding mechanism provided between each plate and the door leaf framework, for making the position of each plate on the framework permanent during a paint processing of the door leaf framework; and an adjustable attachment mechanism for each plate so that each plate is mounted on the door leaf framework with a sliding mounting clearance for adjusting the position of each plate relative to the framework when the door leaf is mounted on the automobile body and before the paint processing.

Description

TECHNICAL FIELD OF THE INVENTION[0001]The invention relates to a device for attaching an opening leaf to the body of a motor vehicle, said device comprising:[0002]at least one panel, which is associated with at least one hinge of the opening leaf and is mounted on a framework of the opening leaf, such that at least one screw, which is integral with the panel, engages with an orifice associated with said hinge and protrudes through said framework of the opening leaf,[0003]bonding means, which are placed between each panel and the framework of the opening leaf and are intended to make the position of each panel on the framework permanent during a painting treatment step of the framework of the opening leaf.[0004]The invention also relates to a method of attaching an opening leaf to the body of a motor vehicle by means of an attachment device of this kind comprising at least one upper panel and one lower panel, which are each associated with a corresponding hinge of the opening leaf, t...
